LITERATURE REVIEW
This research centers on development of spare part inventory management
system. Current researches in spare part inventory management include by Li & Kuo ,
Porras & Dekker, Vereecke & Verstraeten , Baron et. al., Dekker et al. ,
Aronis et al., Jin & Liao, Cobbaert and Qudheusden , Kattan and Adi ,
Chou andHuang, and Mohd-Lair et al. . Li & Kuo , in their journal titled
Automobile Spare parts in a central warehouse, used the Enhanced Fuzzy Neural
Network (EFNN) and Enhanced Fuzzy Neural Network with randomly initialized
connection weights(EFNNR) as their inventory control method.
They compared the two techniques to see their differences. They found that the EFNN
is much better than EFNNR because it avoids out of stock at the price of least stock cost.
Porras & Dekker said that ex-ante is more relevance than ex-post, which is hard to
be implemented. They used the Willemain’s bootstrap method, Empirical distribution of
lead time demand, Normal Distribution, Poisson Distribution and (s,nQ) inventory
model. They found that the inventory models can save money and improve service
levels. Vereecke & Verstraeten used integration of inventory model with two
demand classes (r, r, Q) model with poison distribution. The Spare Part Inventory
Management System (SPIMS) for the A-ARAMCO Enterprise.
This research used service level, average demand, costs and lead time as their
performance measure. They found the reorder point that gave satisfying
result in term of the service levels. Baron et. al. used the stochastic (s, S) approach in
their research. They considered the problem with perishable items (i.e. medicine or
food with expiration date). The performance of the above approach was measured
using costs and lead time of the inventories. The numerical study on the heuristics
shows that they are accurate. When the exact analysis is not possible and the lead time
is relatively short,...
